SPECIFICATION forming part of Letters Patent No. 739,113, datedSeptember 15, 1903.

7 Application filed June 20,1903. Serial No. 162,300. (No model.)

To all whom it near/,7 concern:

Be it known thatl, ORREN A. SAWYER, a

Lowell, county of Middlesex, State of Massachusetts, have invented anImprovement in Automatic Filling-Replenishing Looms, of which thefollowing description, in connection with the accompanying drawings, isa specification, like characters on the drawings representing likeparts.

This invention relates more particularly to looms wherein the runningfilling 'is automatically replenished at'the proper timeas, forinstance, in the Northrop loom, one form of which is shown in UnitedStates Patent No. 529,940, the running shuttle being provided with afresh supply of filling transferred from a feeder or hopper by suitabletransferring means. If the shuttle is not properly boxed,filling-replenishment is prevented by or through a shuttle-feeler, whichdetects the improper position of the shuttle in the replenishingshuttle-box and through intermediate devices governs the operation ofthe transferring means. While the feeler thus detects the improperposition of the shuttle, it does not ordinarily correct the fault, andthe filling-replenishing is retarded until the shuttle is properlyboxed. When the mechanism is nicely adjusted, this delay 11] ay beobjectionable, particularly in so-called feeler-looms, -whereinfilling-replenishment is effected when the filling in the shuttle issubstantially exhausted.

In the present invention the shuttle-feeler is so constructed andarranged that if the shuttle is only slightly out of proper position itwill be pushed into the shuttle-box into position forfillingreplenishment without delaying the latter for two or more picks.Means are also provided to relieve the binderpressure, so that thehoming of the shuttle can be easily effected by the shuttlefeeler,Should the shuttle be so far out of. the box that it cannot be pushed inby the shuttletle-feeler in normal position, with the lay back. Fig. 4is a similar view, but showing the lay nearly forward and the shuttlefeeler in position to detect improper position of the shuttle andcorrect the same if the shuttle is not too far out of the box; and Fig.5 is a detail viewed from the righthand side of the loom of theshuttle-feeler and some of the adjacent parts of the apparatus.

- of the replenishing shuttle-box and the shut- The lay A automaticallyself-threading shuttle S, the feeder F, Figs. land 2, to hold thefilling supplies or carriers 1), Figs. 3 and 4, the transferrer f,having the depending end f, the notched dog m carried by the latter andto be engaged by the bunter O on the lay to effect change of filling,and the controlling rock-shaft d, to be rocked in the the upper end ofwhich forms the shuttle feeler, to be described, said arm having afinger n (see Fig. 5) to engage a lug m on the arm m carrying thenotched dog W, the arm 61 on the rock-shaft (1 being held by spring Sagainst a pin 30 on the arm Y,'substantially as in Patent No. 683,423,except that herein the hub y of armY is not laterally movable onthe-fulcrum-stud a.

Someof the parts just referred to are omitted in Figs. 1 and 2 for thesake of cl'earness, as they are fully illustrated in Figs. 3, 4, and 5.

Referring to Figs. 1 and 2, the protector rock-shaft p, dagger 12thereon, the upturned binder-linger p to cooperate with the binder B ofthe replenishing shuttle-box at the righthand end of the lay, Figs. 3and 4, may be of usual construction and operate in well-known manner.Herein a strap or band 19 Figs. 1 and 2, is shown as looped at one endabout the lay rocker-shaft A and extended upward to a short arm orfinger p on the protectorshaft 1), the strap being long enough to beslack when the lay is back, as shown in Fig. 1. A rod 20 is rigidlysecured to brackets 21, one of said brackets being bolted to each of thecloth-roll stands F as shown in Figs. 1

and 2, the brackets supporting the pivotedlieved, and when the shuttleis in the replete ishin g shuttle-box it can be easily pushed intoproper position by the shuttle-feeler, as will be described. It is to beunderstood that the binder release does not take place until after thepoint of the dagger has passed the usual frog-lift, so that there is nointerference with.

the usual operation of the protectormechanism. The upper end of the armY is bent rearwardly at Y at such a height that it will extend over thelay just in front of the mouth of the replenishing shuttle-box whenfillingreplenishment is to be effected, provided the shuttle is properlyboxed, and in Fig. 2 the part Y constituting the shuttle-feeler, isshown in such position. Referring to Figs. 3 and 4, said feeleris shapedat its extremity to present a cam-face 71 which is diagonal to thelength of the lay and slightly convex, as herein shown. Now if the endof the shuttle projects beyond the mouth of the shuttle-box,

as in dotted lines, Fig. 4, the cam-face 3 will engage the shuttle justback of its point, and as the lay completes its forward movement the camwill act to push the shuttle into the box in proper full-line position,Fig. 4, for fillingreplenishment, it being remembered that thebinder-pressure is then relieved, as has been described. Of course theshuttle-feeler cannot act in such manner if the shuttle is too far outfor the cam to act as described, but in such case the shuttle-feelerwill be stopped in its movement into operative position and thefilling-replenishing mechanism will be prevented from operating. As willbe understood by those skilled in the art, the shut-tlefeeler isnormally maintained in the position shown in Fig. 1, but when therock-shaft d is turned in the direction of the arrow 50 to causefilling-replenishment the lifting of arm (Z permits the dog 11? to moveinto the path of the hunter C and the shuttle-feeler is swung rearwardlyto attain the position showntioning of the shuttle in the shuttle-box,said means yielding when the location of the shuttle precludespositioning thereof, and'mechanism to render said means operative by'orthrough an abnormal condition of the filling.

2. In aloom,the lay provided with ashnttlebox, and swinging meansmounted independently of the lay to normally insure proper positioningof the shuttle in the shuttle box,

said means yielding upon engagement with the shuttle if the location ofthe latter preeludes positioning thereof.

3. In aloom, the layprovided with a shuttlebox, swinging means mountedindependently of the lay and adapted when rendered operative to normallyinsure proper positioning of the shuttle in the shuttle-box, said meansyielding upon engagement with the shuttle if the location of the latterprecludes positionin g thereof, and mechanism to render said meansoperative upon the occurrence of an abnormal condition of the filling.

4. In aloom, the lay provided with a shuttlebox, a cooperating binder,means to relieve the binder-pressure as the lay beats up, and meansrendered operative by or through an abnormal condition of the filling tonormally insure proper posilioning of the shuttle in the shuttle-box,such means acting when binderpressure is relieved, and yielding when thelocation of the shuttle precludes positioning thereof.

- 5. In a loom, the lay provided with a shuttlebox,'a swinging feelermounted independently of the lay and having a cam-face on its freeend toengage and normally insure proper positioning of the shuttle in thesl1uttle-box;-said feeler being retracted by engagement with the shuttlewhen the location of the latterprecludes positioning thereof, andmeans-to efie'ct the movement of the feeler into operating position.

6. In aloom, the lay provided with a shuttlebox, a pivotallymountedfeelerhavinga camface to engage and normally insure proper positioningof the shuttle in the shuttle-box, said feeler yielding when thelocation of the shuttle precludes positioning thereof, and meansgoverned by or through the filling to render said feeler operative.

7.. In a loom, the lay provided with a shuttlebox, a shuttle, a movablefeeler having a camface to engage and normally insure proper Ipositioning of the shuttle in the shuttle-box, the feeler yielding whenthe location of the shuttle precludes positioning thereof, means torelease the shuttle from binding-pressure in the shuttle-box at the timethe feeler acts, and means to render the feeler operative to coaet withthe shuttle.

S. In a loom provided with automatic fillingreplenishing mechanism, alayhaving a shuttle box, means acting normally to insure proper positioningof the shuttle in the shuttle-box when filling-replenishment is to beeffected, and connections between said means and the replenishingmechanism to prevent the operation of the latter when the location ofthe shuttle precludes positioning thereof.

9. In a loom provided with automatic fillingreplenishing mechanism, alay having a shuttle-box, a feeler moved automatically into position tonormally insure proper boxing of the shuttle when filling-replenishmentis to be effected, and connections between the feeler and thereplenishing mechanism to prevent the operation of the latter when thelocation of the shuttle precludes boxing thereof by. the feeler.

10. In a loom provided with automatic fillling-replenishing mechanism, alay having a shuttle-box, shuttle -binding means, a feeler automaticallymoved to normally insure proper boxing of the shuttle whenfilling-replenishment is to be effected, a device to render said bindingmeans inoperative at such time, and connections between the feeler andthe replenishing mechanism to prevent the operation of the latter whenthe location of the shuttle precludes boxing thereof by the feeler.

11. In a loom provided with automatic fill-- position to normally insureproper boxingv of the shuttle, said feeler yielding upon engagement withthe Shuttle when the location of the latter precludes proper boxingthereof by the feeler, and connections between saidfeeler and thereplenishing mechanism to prevent the/operation of the latter when theshuttle cannot be boxed.
